Monoblok: a tiny NATS-ish pub/sub server that conditions noisy feeds before they fan out

I’ve recently reified a pondering I’ve had for some time. It has come to life as monoblok: a small partially NATS-compatible pub/sub daemon written in Zig. There are two features that set it apart: a last-value cache on every subject, and a signal conditioning DSL called patchbay, which lets you filter, smooth and re-publish messages at the broker, before any subscriber sees them. It is an experimental toy at this point, but the ideas are quite nice....
